JAMES E. BURTON, OF WHITE'WATER, WISCONSIN.

DRAG ATTACHMENT FOB PLOW/S.

To all whom it may concern:

Be it known that l, JAMES E. BURTON, a citizen of the United States,residing at lVhitewater, in the county of Vl alworth and State oflVisconsin, have invented certain new and useful Improvements in DragAttachments for Plows, of which the following is a specification.

This invention comprehends certain new and useful improvementsin dragattachments for plows of the walking type, and the invention has for itsprimary object a simple, durable and efficient construction of de viceof this character in which the pulverizer or other drag implement willswing free at the rear of the plow and close to the same, laterallyconsidered, whereby it will not tend to tilt the plow or influence thedi rect draft thereof.

The invention also has for one of its main objects to provide a dragattachment in which the device supporting the drag may be permitted tohave a slight lateral yielding movement, axially considered, so as toavoid any undue strain upon the parts of the drag attachment, or uponthe plow itself, or the hands of the operator grasping the handles ofthe plow.

The invention also has for its object a simple device of this characterby the use of which the drag device may be held at the left-hand side orright-hand side of the plow with equal facility. And the inventionfurther aims to generally improve this class of devices and to make themmore useful and commercially desirable.

"With these and other objects in view as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which:

7 is a rear perspective view of another embodiment of my invention,illustrating the drag device in an operative position in full lines andin a inoperative position in dotted line Fig. 8 a side elevation of aportion of this embodiment of the invention, a par being shown insection; Fig. 9 is an enlarged detail perspective view of a part of thismodification; and, Fig. 10 is a detail perspective view of a devicewhich may be employed to secure in place the drag manipulating handle.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings and now particularly to Figs. 1 to 6inclusive, the numeral 1 designates the beam, 2 the mold board, 8 thehandles, at the handle braces, and 5 the clevis of a walking plow whichmay be of any desired conventional con struction or design.

In carrying out my invention, I preferably secure to the beam 1 of theplow, upper and lower clamping bars (5 secured in place at any desiredpoint along the length of the beam by means of tie bolts 7. The upperclamping bar 6 is preferably formed with a transversely extending seriesof upwardly projecting bosses 8, said bosses being formed with bayonetslots 5) leading to annular recesses, whereby there may be se cured toany of the bos s a pin or post 10 formed with an angularly disposedlower end 11, so that the pin or post may be easily inserted in anddetached from the boss and be securely held a gainst accidentaldisplacement. A roller 12 is preferably journaled on the post. By meansof this laterally ex tending series of bosses 8 and the detachablearrangement of the post 10, the latter may be shifted from one boss toanother so to vary the line of draft of the drag devices hereinafterspecifically described, and the angular position thereof.

18 desiginites a. frame which is formed with a longitudinally extendingslot l t by which. it is mounted for a longitudinally slidahle, turningand tilting movement on the post 10, friction being reduced by means ofthe roller 12 designed. to directly engage the side walls of the slot.frame 13 are projected upwardly, as indicated at 15, and are recessed intheir upper extremities to form seats for a drag sup- The ends of theporting rod 16, said rod being insured against displacement from therecesses of the upturned ends 15 by means of cotter pins 17, as clearlyillustrated in the draw ings. The rear end of the rod or bar 16 isconnected to and designed to directly sup port a drag device 18 whichmay manifestly be in the nature of a pulverizer, harrow of any type, orany other desired drag. The forward end of the rod 113 is bentlaterally, as indicated at 19 in advance of the frame 13, and a bolt 20is designed to extend through the laterally projecting forward end 19 ofthe rod, and also through one of a pair of laterally spaced andforwardly projecting cars 21 formed on the forward end of the frame 13.A compression spring 22 encircles the bolt 20 and is designed to bearagainst the laterally projecting end 19 and to react against thesubjacent ear 2l, so as to permit the rod 16 to have a li1n ited turningmovement about its longitudinal axis, thereby relieving from the plow,to a considerable extent, the lateral strain that may be imposed uponthe drag device. By providing a pair of these cars 21 it is obvious thatthe device may be arranged at either the right-hand or left-hand of theplow, the rod 16 being reversed axially and the bolt 20 passing throughthe end 19 and the then subjacent car 21.

In order to adjust the drag device forwardly or rearwardly alongside ofthe plow, the frame 13 is formed with any de sired number oftransversely extending apertures 23, so that a bolt 2-1- may be passedthrough corresponding apertures on opposite sides of the slots 11 andthereby limit the relatively rearward movement of the rod 16 and frameas regards the post 10 which sustains directly the draft of the drag.

A handle 25 is connected to the rear end of the drag supporting rod 16and projects upwardly therefrom, whereby the operator may easily liftthe rear end of the rod and raise the drag, and by sliding the rod andframe 13 forwardly and by moving the rear end of the rod and dragupiardly and inwardly, the drag may be easily supported in aninoperative position on the handles 3, where it will be out of the wayand its weight will be properly distributed on the plow and not tend tolaterally overbalance the latter.

Preferably one of the handles 3 carries a laterally projecting hook 26which normally lies underneath and spaced from the rod 16 in theoperative position of said rod, so as to limit the downward movement ofthe rod, should the drag device be unduly lowered for any reason,thereby catching the rod and preventing it from striking the mold board2, for it is to be understood that in the preferred arrangement of thedra the ment therein.

same will lie close behind the mold board and will avoid any side draftor influencing of the plow. If desired, I may secure to one of thehandles 3, above the rod 16, a clip 27 provided with an apertured lug 28in which a downwardly spring pressed stem 29 works, said stem beingformed, as by a recessed lower end 30, to engage the rod 16 and preventthe drag from jumping up. It is to be noted that in the normalincompressed or untensioned position of the stem 29, a space will beleft between the lower end of the latter and the hook 26, whereby therod may be easily disengaged from the stem in the operation of swingingthe red at its rear end upwardly and inwardly so as to rest the drag 18upon the handles 3. I do not regard this spring device as essential, butit may be found useful under some circumstances.

It is to be understood that my invention is not limited to theconstruction, arrangements and proportions of the parts illustrated inFigs. 1 to 6 of the drawing, but that various changes may be madewithout departing from the scope of the invention as defined in theappended claims. F or instance, another embodiment of the invention isillustrated in Figs. 7, 8 and 9, where 6 designates the clamping barsadapted to be secured to the beam of a plow, the upper bar being founedwith one or more bayonet slotted bosses 3 to which a transverselyapertured eye 31 is detachably connected for a turning movement about asubstantially vertical axis. In this embodiment of the invention nowbeing referred to, the drag supporting rod or bar, here designated 16 isconstructed in hingedly connected sections, the foremost one of which isdesignated 32, the same being formed with a laterally projecting end 33adapted to be slipped into the eye 31 for a rocking move The oppositeend of the section 32 is forked, as indicated at 34 to ac commodate theframe 13 said frame being formed with any desired number of transverselyextending apertures 23 to receive a bolt 35 which connects the framewith the forked end of the section. The frame 13 is substantiallyidentical in function and purpose with the frame 13 before described,and is provided with upturned ends 15 formed with recesses in which therear section 36 of the drag supporting rod is mounted. This last namedsection is formed with a laterally extending forward end 19, and a bolt2O" is adapted to pass through said end and through either one of a pairof apertured ears E21 projecting forwardly from the front end of theframe 13 said ears being arranged in laterally spaced relation to eachother, as best illustrated in Fig. 9. By the provision of the two ears,just as in the case of the embod ment first described, the rod 36 may bereversed axially according as it is desired to support the drag device18 at the right-hand side or left-hand side of the plow. The spring 2%encircling the bolt 520, permits the rod 36 to have a limited turningmovement about its longitudinal axis just has heretofore been describedin connection with the rod 16.

The operative position of that form of the invention illustrated inFigs. 7, 8 and 9 is shown in full lines in Fig. 7, and in order to raisethe drag 18 and rest it in an operative position, it is only necessaryfor the operator to grasp the handle 25 and push forwardly on the rodsection 36, the jointed connection between the frame 13 which holds thesection 36 in place by means of the bolt 20 and cotter pin 17 or thelike, and the section 32, and the jointed connection between the section32 and the eye 31, permitting the drag device 18 to be moved forwardlyand thence swung inwardly over the handles of the plow, the parts beingthen in their inoperative position, illustrated in dotted lines in Fig.7.

In order to secure the handle 25 in place (and this applies to any formof my invention) I may secure said handle, preferably by a single bolt,to either one of a pair of recessed lugs 37 extending upwardly anddownwardly from a collar 37 adapted to he slipped over the rearlaterally extending end of the drag supporting rod, said collar beingformed with upper and lower spaced laterally projecting lugs 38 adaptedto extend over and underneath the main part of the rod at the rear endof the latter, so as to assist in rigidly connecting the handle to therod. If desired the collar 37 may be se-- cured to the red by a setscrew 39.

From the foregoing description in connection with the accompanyi11gdrawings, it will be seen that I have provided a very simple, durableand ellicient construction of drag attachment for plows, whereas thedrag will be freely and loosely supported in its operative position,and, lying so close to the plow, back of the mold board thereof, willnot influence the motion of the plow, while in the inoperative positionof the drag, it will be supported in a position where it will not tendto unduly tilt or overbalance the plow laterally.

Having thus described the invention, what is claimed as new is:

1. A. drag attachment for plows, comprisa support, a frame carried bysaid support, a rod mounted for an axially turning movement in theframe, a drag device car ried by said rod, and means for limiting theaxial movement of the rod, the frame being mounted for a movement on thesupport in a direction in line with the length of the rod.
